- ACRONYM
- hypothesis1. Does participating in the self-help intervention "This is your life", with or without emailcounseling leads to a significant higher level of emotional, psychological and social well-being compared to a waiting-list control group?
2. Are the effects of the self-help intervention "This is your life" maintained at 6 and 12 months follow-up?

3. Are the effects of the self-help intervention "This is your life" with or without emailcounseling mediated by the theoretically effective components (positive emotions, use of strengts, optimism, self compassion, resilience, and positive relations)?

4. Does participating in the self-help intervention "This is your life" with or without emailcounseling leads to significant more flourishers?

5. Which groups of participants benefit from the self-help intervention "This is your life", and which groups not or less? (for example men/women, high/low education, languishers/moderately mentally healthy participants)

- InterventionsStudy design:
A randomized controlled trial with three conditions:
1. Experimental condition 1: the self-help intervention "This is your life, experience the effects of positive psychology" with weekly proces and content e-mail counseling.
2. Experimental condition 2: the self-help intervention "This is your life, experience the effects of positive psychology" without e-mail counseling, but with a weekly e-mail containing frequently asked questions and answers (FAQ).
3. Control condition: a waiting list control group, participants receive the self-help intervention after six months.

Participants in the experimental conditions have 12 weeks to independently follow the self-help intervention consisting eight lessons. Topics that will be covered are: the importance of positive emotions, discovering and using strengths, optimism and hope, being friendly to yourself, coping with adversity, developing positive relationships, and connectedness and giving. The intervention gives information and practical exercises which the participant can practice independently. The group with e-mail counseling will also have weekly contact with their counselor about their progress and possible problems. The control condition consists of participants who are on a waiting list and they will receive the self-help intervention after six months.
- Primary outcomeThe primary outcome is the level of well-being, measured with the MHC-SF.
- Secondary outcomeSecundary study parameters/outcome of the study (if applicable):
Secondary outcomes are flourishing, mental illnesses (depression and anxiety), positive and negative emotions, resilience, use of strengths, optimism, self-compassion, positive relationships, health care use and productivity losses. Demographics, personality characteristics and positive and negative life events during the last 12 months will also be measured.
- TimepointsQuestionnaires are taken online before (T0) and after (T1) the intervention, six months after the intervention (T2) and 12 months after the intervention (T3).

- Brief summaryPrevention and reduction of mental illnesses are central in mental health care. Until now, the emphasis was on prevention and treatment of mental disorders, but recently it is argued that it is highly relevent to invest in well-being as this will probably contribute to the prevention of mental disorders. Individuals who score high on emotional, psychological and social well-being are also known as "flourishers". Promoting flourishing is a new field in positive psychology. Individual interventions are mostly designed to strengthen individual competencies that improve emotional, psychological and social well-being. Examples of these competencies are strengtening positive emotions, examining values, intrinsic needs and strengths, optimistic goal striving, maintaining positive relationships and coping with adversity (resilience). A recent meta-analysis shows that there is a diversity of positive psychology interventions with small but significant effect sizes for wellbeing. However, these interventions are mostly minimalistic, therefore, more durable effects are not yet expected from these interventions. It is concluded that a more intensive, comprehensive positive psychology intervention is needed to promote well-being and flourishing in the population. The University of Twente has now developed a self-help intervention for adults with a low or moderate level of well-being: "This is your life, experience the effects of positive psychology".

The aim is to study the effectiveness on well-being of the self-help intervention "This is your life, experience the effects of positive psychology" in a randomized controlled trial. We expect that the intervention, with or without e-mail counseling, is superior to a waiting list control group.
